OF NEW YORK, N. Y.

IMPROVEMENT IN WHIFFLETREES.

Specification forming part of Letters Patent No. 203,146, dated April 30, 1878; application filed April 10, 1878.

To all whom it may concern:

. Be it known that I, ARCHIBALD HANCE, of the city, county, and State of New York, have invented a new and useful Improvement in Whiffletrees, which improvement is fully set forth in the following specification, reference being had to the accompanying drawings, in which- Figure 1 represents a plan or top view of .a whiftletree embracing my invention. Fig. 2 is a side elevation thereof. Fig. 3 is a front view of the same.

Similar letters indicate corresponding parts.

My invention relates particularly to whittletrees for horse railroad-cars, its object being mainly to prevent the ends of the oscillating draft-bar from striking against the dash-board gt the vehicle, and to support the ends of said It consists in a vertical frame or a bar hav-' ing a .rearwardly-extending clip ,for attachment to the vehicle, and a forwardly-extending clip, provided on its lower portion with a segmental guide-bar, having rearwardly-extending arms, bent upward at their ends to form stops for preventing an excessive oscillation of a whiflietree pivoted in said clip and supported by said arms, as will be hereinafter more particularly described.

In the drawing, the letter A designates the oscillating draft-bar, andB is the supportingframe of my whiffletree.

In order to adapt the frame B to be coupled to a horsecar or other vehicle, it is constructed with a clip, B, having one or more holes for the reception of a coupling-pin. I also provide such frame with a secondary clip, B in which the draft-bar A is held by a pin, a. This bar is preferably curved, as shown in Fig. 1.

The letter O designates the stops, which I use for the purpose of limiting or regulating the motion of the draft-bar A. These stops are situated in a horizontal plane with the bar A-or, in other words, they are situated in the path of such bar; and in order to bring the stops in this position, and at the same time form a bearing for the outer portions of the bar, I form'or affix the stops on the respective ends of a segmental guide, D. This guide is constructed as part of the frame B, and it is arranged concentrically to the pivot b, the same being composed of a flat strip of metal or othermaterial, and the stops 0 being formed by simply bending the ends of such strip upward, as clearly shown in Fig. 2. The stops 0, however, can also be arranged in other ways-as, for instance, the same can be affixed to arms projecting from opposite sides of the supportingframe B.

I prefer to arrange the stops Gin such relation to the frame B that they lie in a plane extending at right angles to such frame contiguously to the axis of the draft-bar A; but this position can be varied to suit the vehicle to which my whiffletree is to be attached.

It will be seen that while the stops 0 permit the draft-bar to describe its required motion, at the same time prevent either end thereof from passing rearward beyond a certain point, and hence the ends of the bar can easily be prevented from striking against the vehicle to which the whole is attached, whereas by the segmental guide D a vibrating or shaking motion of the bar is to a great extent prevented.

If desired, the strip composing the segmenta1 guide D may be duplicated, in order to increase the effect of the guide.

What I claim as new, and desire to secure by Letters Patent, is-

1. The frame B, having the clip B for attachment to the vehicle, and clip B provided with the segmental guide-bar D, having rearwardly-extending arms, bent upward to form stops 0 O, and adapted to receive a whiffletree, substantially as described.

2. The combination, with the frame B, having the clip B for attachment to the vehicle, and clip B provided with the segmental guide-bar D, having rearwardly-extending arms, bent upwardly to form stops 0 O, of the oscillating whiflietreeA and bolt a, substan tially as described.

In testimony that I claim the foregoing I have hereunto set my hand and seal this 6th day of March, 1878.
